WIRELESS COMMUNICATION SYSTEM, SIM CARD, MOBILE COMMUNICATION TERMINAL, AND DATA GUARANTEEING METHOD - The loss of data stored in a secure memory card, such as a SIM card, due to the physical destruction thereof is prevented. A host unit performs card authentication of a memory card, and transmits update data for the memory card by security communication to update data when the result of the authentication is OK. Then, the host unit outputs a request for mirror-updating the card data to a base station server. When an access is permitted, the card data is transmitted to the base station server via the host unit to mirror-update the card data. When the mirror-updating of the card data is completed, the base station server returns a completion confirmation to the host unit, so that a data backup process is completed. By thus causing the base station server to mirror-update the data in the memory card, the loss of the stored data is prevented.

The isolator includes an isolator element and a transmitting means. The isolator is disposed so that the isolator element is on light paths of input lights and that the transmitting element is on a light path of an output light. The isolator element is shared among the light paths of the plurality of input lights. The isolator element intercepts lights propagating in an opposite direction to the input lights and prevents coupling of the lights to input ports. The transmitting element transmits the output light and couples it to an output port.

COUNTER-ROTATING AXIAL-FLOW FAN - A counter-rotating axial-flow fan includes a housing that is constituted from a first divided housing unit and a second divided housing unit. Engaging members and first stopper portions are integrally formed with a first flange portion of the first divided housing unit. The first stopper portions are arranged adjacent to the engaging members. Engaged members and second stopper portions are integrally formed with a second flange portion of the second divided housing unit. The second stopper portions are arranged adjacent to the engaged members. The second stopper portions have leading ends that are abutted onto leading ends of the first stopper portions when the engaging members are completely engaged with the engaged members. Thus, damage of the first and second divided housing units is prevented when the first and second divided housing units are coupled.
